<h1>Version 8.4.3 (released 29<sup>th</sup> May 2018)</h1>

<div class="box">
    <h1>Take Notice</h1>
    <p>
      The packages on this page include only the GHC compiler. For most users,
      we recommend installing a
      <a href="http://www.haskell.org/downloads">proper Haskell distribution</a>
      instead of GHC alone. A distribution includes a recent GHC release as well
      as other important tools (such as <code>cabal-install</code>, for
      installing libraries), and potentially a broader set of libraries known to
      work together.
    </p>
</div>

<div class="box">
    <h1>Bundled packages and cabal-install</h1>
    <p>
      GHC 8.4 only works
      with <a href="http://hackage.haskell.org/package/cabal-install"><code>cabal-install</code></a>
      version 2.2 or later. Please upgrade if you have an older version of
      <code>cabal-install</code>.
    </p>
</div>

<div class="box">
    <h1>Optional LLVM dependency</h1>
    <p>
      GHC has an optional code generator targetting
      the <a href="http://www.llvm.org/">LLVM</a> compiler framework which can
      produce faster code for some programs. If you would like to use the LLVM
      backend, you'll need to install LLVM 5.0 from
      an <a href="http://llvm.org/releases/download.html#5.0.1">upstream binary
      distribution</a> or via your distribution's package manager.

    <h2>Distribution packages</h2>
    <p>
      GHC is packaged for a number of operating systems and
      distributions. While they may lag behind the latest GHC
      release, advantages such as dependency checking and ease of
      uninstallation mean we recommend using them anyway, unless
      you have a particular need for new features or bug fixes.

    <h2>Binary Packages</h2>

    <p>
      The operating system-specific packages (e.g. RPM or <tt>.deb</tt> packages
      on Linux) are generally a better bet than the vanilla <tt>.tar.xz</tt>
      binary bundles, because they will check for dependencies and allow the
      package to be uninstalled at a later date.
    </p>

    <p>
      However, if you don't have permission to install binaries on your system,
      or you want to install somewhere other than the default place
      (<tt>/usr</tt> or <tt>/usr/local</tt> on a Unix system), then you'll need
      to use a <tt>.tar.xz</tt> binary bundle.
    </p>

    <p>
      SHA-256 hashes for all of these binary distributions are
      available <a href="$downloads_url$/SHA256SUMS">here</a>.

    <h2>Source Distribution</h2>
    <p>
      The source tarballs provide everything necessary to build the compiler,
      interactive system, and a minimal set of libraries. For more information
      on building, see
      the <a href="http://hackage.haskell.org/trac/ghc/wiki/Building">building
      guide</a>.
    </p>
    $tarballs("src")$

    <p>
      The testsuite provides a thorough set of tests for validating your build.
      Unpack this tarball on top of the regular source distribution in order to
      run the testsuite (see
      the <a href="https://ghc.haskell.org/trac/ghc/wiki/Building/RunningTests">testing
      guide</a> for details).
    </p>
    $tarballs("testsuite")$

    <p>
      Building on Windows requires a set of additional tools. Extract this tarball on
      top of the regular source distribution,
    </p>
    $tarballs("windows-extra-src")$

    <p>
      The source distribution needs an installed GHC (version 8.0 at least). If
      your platform isn't currently supported with a binary distribution, then
      you'll need to consult the section
      on <a href="http://hackage.haskell.org/trac/ghc/wiki/Building/Porting">Porting
      GHC</a> in the Building Guide.
